SENSITRON S4590PR PROPANE detector. 4-20 mA. 0-100% LFL

The SMART3-R detector allows the detection of various gases in non-classified areas, laboratories and machine rooms. For the detection of flammable gases it is equipped with a catalytic sensor. This sensitive element provides optimal precision and selectivity with most explosive gases, avoiding false alarms as much as possible. The status of the detector is constantly displayed by 4 intelligent LEDs that illuminate the transparent ring and notified by an internal buzzer. The SMART3-R detector has a 12-24 Vdc power supply as standard, but a high voltage version can be requested. As outputs, the detector has 3 relays, an RS485 serial connection and an analog 4-20 mA connection (not present in the high voltage version). The case is made of polycarbonate, with a total size of 130 x 130 x 74 mm; has two outputs with M20 cable glands already mounted. On the sides there are pre-formed guides that can be drilled to add up to 6 M16 cable glands. As a further option, the SMART3R detector can be equipped with a remote head, connected via a RJ12 6P6C cable.
